Vietnam’s manufacturing industry grows rapidly
Vietnam is not only a production base for labor-intensive industries such as clothing and footwear, wood processing, but also increasingly popular with electronics manufacturers in recent years. Multinational companies such as Samsung, Intel and Microsoft, Nokia mobile phones have expanded production in the country. In addition to these existing companies expanding production, other overseas electronics companies have also continued to influx, driving the total output value of the Vietnamese electronics industry to rise steadily, with a compound annual growth rate of 59% from 2008 to 2013, which is higher than the growth of the overall manufacturing output value. Rate (24%) more than doubled. Since 2013, electronics have become Vietnam’s largest export cargo.
Vietnam’s export growth has been significant, mainly driven by foreign direct investment.
According to the Ministry of Industry and Trade of Vietnam, in 2015, foreign direct investment enterprises accounted for 71% of Vietnam’s total exports, and almost all of the country’s exports of telephones, electronic products, computers and components came from foreign companies. In 2015, the United States, the European Union, ASEAN, China, Japan and South Korea were Vietnam’s main export markets.
In recent years, the main imported products include machinery, equipment and parts, as well as electronics, computers and accessories. Most of the imported machinery and equipment are related to the assembled goods exported. China is Vietnam ’s largest source of imports, followed by South Korea, ASEAN, Japan, the European Union and the United States.
China-Vietnam bilateral trade in 2019
Vietnam has released import and export data for 2019, with China still Vietnam’s largest trading partner, Vietnamese media reported. Data shows that in 2019, the total import and export volume of China and Vietnam reached 116.87 billion US dollars, which is the second consecutive year that the trade volume of the two countries exceeded 100 billion US dollars.
In the nearly $117 billion import and export cooperation, Vietnam’s export to China was $41.41 billion, an increase of only $150 million or 0.36% over the same period last year, and its import from China was $75.452 billion, an increase of $10 billion or 15.3% over the same period last year.
China’s export to Vietnam continues to grow at a high speed, and the Vietnamese market has attracted the attention of Chinese enterprises. In recent years, Chinese enterprises have set off a boom in investing and setting up factories in Vietnam.

Generally speaking, there are 9 indicators for paper towel quality inspection: appearance, quantitative, whiteness, lateral liquid absorption height, lateral tensile index, average vertical and horizontal softness, holes, dustiness, microorganisms and other indicators.
1.Appearance
The appearance of toilet paper, including the appearance of packaging and paper towels. When choosing toilet paper, first check the outer packaging. The packaging seal of the product shall be neat and firm without damage; the package shall be printed with the name of the manufacturer, the date of production, the product grade (superior product, first-class product, qualified product), the adoption standard number, and the implemented hygiene standard number (GB20810 – 2006).
Secondly, check the appearance of the paper. It is clean. There are no obvious dead folds, incompleteness, breakage, hard blocks, grass bands, pulp and other paper diseases and impurities. There should be no serious hair loss or powder loss when using the paper. There should be no residual printing ink in the paper.
2.Quantitative
It means that the weight or number of sheets is not enough. According to the standard, for products with a net content of 50 grams to 100 grams, the negative deviation must not exceed 4.5 grams; for products with 200 grams to 300 grams, the tolerance must not exceed 9 grams.
3.Whiteness
Toilet paper is not as white as possible, it may be that an excessive amount of fluorescent bleach is added. Fluorescent agents are the main cause of dermatitis in women, and long-term use may cause cancer. How to tell whether there is an excessive amount of fluorescent bleach? First of all, it should be natural ivory white with the naked eye, or if the toilet paper is exposed to ultraviolet light (such as a banknote detector), if blue fluorescence appears, it is proved to contain a fluorescent agent. And if the brightness is too low, it will not affect the use of toilet paper, but it means that the raw materials used are poor, so try not to choose this kind of product.
4.Water absorption
You can put water droplets on it to see how fast it absorbs. The faster the speed, the better the water absorption.
5. Horizontal tensile index:
It’s the toughness of paper. Is it easy to crack when used. Pure wood pulp paper has long fiber, high tensile strength, good toughness, and is not easy to break.
6. Softness
This is an important indicator of toilet paper products. Good toilet paper should give people a soft and comfortable feeling. The main factors affecting the softness of toilet paper are the fiber raw material and creping process of toilet paper. Generally speaking, cotton pulp is better than wood pulp, wood pulp is better than wheat straw pulp, and toilet paper with excessive softness feels rough in use.
7. Holes
The perforation index is a limit requirement for the number of perforations on the wrinkled toilet paper. The perforations will affect the use of the paper. The wrinkle toilet paper with too many perforations not only has a poor appearance, but also easily breaks during use, affecting the wiping effect.
8.Dust degree
In simple terms, there is not much dust on the paper. If the raw material is wood pulp, the degree of dust is not a problem. However, if the recycled paper is used as a raw material and the process is not handled properly, it will be difficult to meet the dust standard.
9.Microbes
All in all, good toilet paper is generally natural milky white or ivory, with fine and uniform texture, clean paper surface, no holes, no obvious dead creases, dust, raw grass, etc., while low-grade toilet paper looks dark gray and has Impurities. Touch it with your hands, the toilet paper will lose powder, color, or even hair.
In recent years, more and more customer inspection cases, has gradually become the existence of a lot of foreign trade enterprises habit. In spite of this, there are still many foreign trade enterprises which are misunderstanding on customers’ inspection requirement. In fact, the customer inspection requirement is not our imagination of so bad or so terrible, on the contrary, customer inspection, is also a good way to show supplier’s production power, therefore, in order to the long-term development of the enterprise, when we are faced with customers inspection requirements, don’t appear too panic, also do not appear too lost, as long as we do a good job, strive to make our enterprise management summarized it will be ok. Below are points to help you in the situation.
One, usually do a good job of improving and upgrading the production of the enterprise
Why do customers implement factory inspection? Its main purpose is, of course, to further determine the internal strength level of a foreign trade enterprise, because only by cooperating with a high-level foreign trade enterprise can the customer obtain a stable and reliable supply of products. Therefore, in order to effectively pass the customer inspection assessment, our own strength is quite important. “Strike iron also need their own hard”, no matter how the customer factory inspection, as long as our strength is strong enough, then through the customer inspection plant is also very easy. Therefore, it is very important to improve our own strength level. We should integrate such promotion and improvement work into our daily work practice, constantly learn from it, strengthen management, and strive to achieve scientific norms and guidance for enterprise production management.
Two, make certain preparation
Even if the foreign trade enterprises usually do well, in order to effectively pass the customer inspection assessment, we still have to do a certain amount of preparation, otherwise we have the strength, but because of some small details and failed to pass the customer inspection assessment, then we are not worth the loss. Under normal circumstances, the customer inspection, generally come from two aspects of hardware and software, so if the foreign trade enterprises have enough confidence to grasp through the enterprise inspection appraisal, still cannot treat STH lightly at this moment, should be within the scope of the budget allows, in advance of their hardware and software support for a reflection and introspection, completes the corresponding correction work, to fight for at the time of inspection of customers, give customers a good impression, and thus promote bilateral trade cooperation smoothly.
Three, want to achieve the promotion on the idea
Different foreign trade enterprises hold different views on the matter of customer inspection. Some foreign trade enterprises hate it deeply, fear it and refuse the customer’s request for inspection. Such foreign trade enterprises actually shut their business out. Some foreign trade enterprises for the customer inspection fear that they can not pass the customer inspection of the factory, the whole customer inspection of the factory for them like torture pain, in fact, these situations are ultimately a matter of concept. In fact, the customer inspection is a win-win good ah, customers can make friends with you such a good business partner, at the same time after the completion of the inspection will give you some production improvement advice, this for foreign trade production enterprises themselves, is also a favorable thing ah. Therefore, foreign trade enterprises should take the initiative to change their concept of customer inspection, and strive to promote the whole concept to develop in a positive direction.
Four, positive acceptance
Finally, in fact, the customer inspection is to examine the normal for foreign trade company, as a foreign trade company completely don’t panic, as long as do their share of the work, actively accept in idea, in practice, the better to participate in the customer in the practice operation of inspection, to promote the entire customer inspection smoothly and inspection qualified by itself, eventually to promote bilateral trade cooperation smoothly.
